(KMOV.com) -- While most were eating or watching football, some residents were in tents outside of retail shops; and some of them had been there for two days.

Once the sun goes down on Thanksgiving, the Super Bowl of shopping just hours away, and one presale camper has been waiting for it all year.

“We got out here about 10 minutes to six Tuesday morning,” said Bonita Brock.

Brock has lined up every year, forgoing the traditional meal for Black Friday deals. And she always goes to the same store.

“It’s just nice coming out here to Best Buy and most of the time they always have good deals,” she said. “It ain’t certain things you gotta get because once you get here you might find a whole lot more. But it’s really nice and that’s why we come every year.”

Brock is just one of the estimated 147 million who will shop Thursday night and Friday, helping generate an expected $21 billion for the economy.

Police vow to keep shoppers safe, promising extra patrols all night and all day Friday.
